So if i understand well, the dev is going trough a difficult moment, probably with his marriage if i understand well and if he recover (which i hope even if he didn't continue the game), maybe he will continue the game. So it's more of a pause than a abandoned but sometime a pause can lead to abandoned.
Either way, the development of the game was really slow these last months. (i'm following this project since at least 6 years ). I'm kinda sad that the game is in this state but i'm not the one who is going trough hard stuff.
I'm gonna see how it develop and gonna come in a few month, hoping for the best : )
PS: for the hot headed here, take a bit of stoicism, it help. Meaning screaming and complaining won't make the dev coming back, it just making you unhappy and potentially making other annoyed. Learn to accept what you can't control (like the dev won't coming back now depending of you writing stuff here) and take responsibility for what you can control (like accepting the harsh reality, focusing on something else and coming back later, trying to manage your emotions). Hope it doesn't sound too harsh, because it's not the point.
